Fault finding

In the event of a Profibus module failing to respond check the following:

CAUTION

The Profibus Module contains no user serviceable parts. Do not disassemble the module.

Table 7 - Fault finding guide

Symptom

Fault

Power LED not lit

No DC supply or internal regulator faulty.

Off-line not lit and Error LED flashing.

Address selection is above 125 or 0, correct the
address and re-power unit.

Off-line LED is lit and Error LED is lit.

Unsuitable parameterisation or configuration,
check extended diagnostics for module number.

Off-line LED is lit and Error LED is not lit.

Check unit’s address matches that being used
by the master. Check Profibus cable connected.
Check Profibus master is on-line.

Power LED is lit and all other LED’s are not lit.

Serial connection to Controller disconnected or
faulty or Controller not powered on.

Data exchange LED is lit but data is not
changing.

Serial connection has become faulty after
entering data exchange. Check extended
diagnostics for serial comms lost indication.
